pollination and greenhouses

[Paul Westberg]

just wondered how anyone was handling the issue of pollination of plants in the greenhouse. I have a hive that moved into my yard and is doing a great job on my soil based beds but so far none of the bees have come to the greenhouse. I have heard that bumblebees are good in greenhouses as they are solitary but pollinate well. How are the rest of you handling this or do you avoid plants that require pollination?

I grow heirlooms so I have to hand pollinate but try to select as many self pollinators as possible. Mechanical separation and time (staggered growing). I grow flowers in the center of my greenhouse to attract bees and butterfly for those that are safe.
